There are four methods of acquiring data: collecting new data; converting/transforming legacy data; sharing/exchanging data; and purchasing data..
What is the sampling frequency of the DAQ?
One of the most important specifications of a DAQ device is the sampling rate, which is the speed at which the DAQ device's ADC takes samples of a signal. Typical sampling rates are either hardware- or software-timed and are up to rates of 2 MS/s..
An ADC takes a continuous analog signal and converts it to a discrete digital signal by taking samples that represent the signal's amplitude at specific points in time. The sample rate (or sampling rate) is the number of samples taken per second.

How does synchronous data acquisition work?
This happens at the sample rate specified for inputs. When doing synchronous data acquisition, the pulse count is read into the buffer by the driver, just as with analog inputs. The application software reads data out of the buffer in blocks, just as with analog inputs.

How fast can a data acquisition device run?
In Windows this can reliably run up to about 1000 samples per second. If another application is running or if the application does a lot of processing the speed may be limited to much less. If the data acquisition device has a buffer, many samples may be transferred during each interrupt.

How to determine the recording capacity of a high frequency equipment?
In order to learn about the equipment’s recording capacity per channel, a quantitative analysis is performed to determine the maximum sampling frequency when using a certain number of channels. This confirms the design of the equipment proposed, for its high frequency data acquisition capacity.

What is data acquisition?
Data acquisition is the sampling of continuous real-world information to generate data that can be manipulated by a device, such as:
a computer
Acquired data can be displayed, analyzed, and stored.

Series of American military satellites
Advanced Extremely High Frequency (AEHF) is a constellation of communications satellites operated by the United States Space Force. They are used to relay secure communications for the United States Armed Forces, the British Armed Forces, the Canadian Armed Forces, the Netherlands Armed Forces and the Australian Defence Force. The system consists of six satellites in geostationary orbits. The final satellite was launched on 26 March 2020. AEHF is backward compatible with, and replaces, the older Milstar system and will operate at 44 GHz uplink and 20 GHz downlink. The AEHF system is a joint service communications system that provides survivable, global, secure, protected, and jam-resistant communications for high-priority military ground, sea and air assets.

Telecommunications standard for the wireless transmission of data through radio signals
Evolution-Data Optimized is a telecommunications standard for the wireless transmission of data through radio signals, typically for broadband Internet access. EV-DO is an evolution of the CDMA2000 (IS-2000) standard which supports high data rates and can be deployed alongside a wireless carrier's voice services. It uses advanced multiplexing techniques including code-division multiple access (CDMA) as well as time-division multiplexing (TDM) to maximize throughput. It is a part of the CDMA2000 family of standards and has been adopted by many mobile phone service providers around the world particularly those previously employing CDMA networks. It is also used on the Globalstar satellite phone network.

Method of encoding digital data on multiple carrier frequencies
In telecommunications, orthogonal frequency-division multiplexing (OFDM) is a type of digital transmission used in digital modulation for encoding digital (binary) data on multiple carrier frequencies. OFDM has developed into a popular scheme for wideband digital communication, used in applications such as digital television and audio broadcasting, DSL internet access, wireless networks, power line networks, and 4G/5G mobile communications.
The word frequency effect is a psychological phenomenon where recognition times are faster for words seen more frequently than for words seen less frequently. Word frequency depends on individual awareness of the tested language. The phenomenon can be extended to different characters of the word in non-alphabetic languages such as Chinese.
